LOCOMOTIVE SPARK-EXTINGUISHER.

SPECIFICATION formingpart of Letters Patent No. 234,274, dated November 9, 1880.

Application filed July 24, 1880. (No model.)

To all whom it may concern Be it known that we, GEORGE A. GUNTHER, of Bath, in the county of Kings and State of New York, and WILLIAM KowALsKI, of Brooklyn, in the county of Kings and State of New York, have invented a new and useful Improvement in Locomotive Spark-Extinguishers, of which the following is a specification.

Figure 1 is a sectional elevation of the imzo provemen t, taken longitudinally with the boiler. Fig. 2 is a sectional elevation taken through the line 00 a, Fig. 1, looking to the left. Fig. 3 is a sectional elevation taken through the line as x, Fig.1, looking to the right. Fig.

4 is a sectional plan view taken through the line y y, Fig. 1.

Similar letters of reference indicate corresponding parts.

The object of this invention is to deaden or extinguish sparks passing out through the smoke-stack of a locomotive.

A represents the locomotive-boiler; B, the smoke-box; O, the smoke-stack, and D the nozzle of the exhaust-steam pipes.

5 E is a pipe leading out from the lower part of the water-space of the boiler A, passing up through the smoke-box B and along the rear side of the stack 0. The upper part of the pipe E is widened, and its rear or outer side 3 is extended up farther than its inner side, and is curved over inward. The widened mouth of the pipe E is covered with a finely-perforated plate, F. At the forward side of the upper part of the interior of the stack 0 is the which extendsfjdown along thegforward part of the said stack, passes through the forward part of the smoke-box B, and passes down through the lower part of'the boiler-shell. In

4 the lower part of the pipe E is a stop-cock, H,

to allow the Water from the boiler A to be admitted to and shut off from the said pipe E when desired.

Though we prefer to take the water from the boiler in the manner herein described, the water may be taken, if desired, from the tanks of the tender, or from any other convenient source, and forced into the pipe E by any suitable means.

The lower end of the smoke-stack O is cov- 5o ered by a wire-gauze plate, I. With this construction, when the engineer has got up steam and is ready to start the engine, he opens the stop-cock or valve H and allows water to be forced into the pipe E by the steam-pressure in the boiler, which water is projected through the sprinkler F across the upper part of the smoke-stack O in a fine spray, and is received in the wide upper end of the pipe G. The water from the pipe E extinguishes the sparks that may be passing out with the blast, and carries them with it into the pipe G, through which the water and the extinguished or deadened sparks pass down to the ground.

We are aware that the sparks have been arrested by a wire-netting and carried down a tube to be extinguished by the water-spray. Our spray-water is forced through the pump or by steam-pressure of the boiler across or diagonally against the cinders blown out by the exhaust-steam, only a small part of the water being carried with the blast, as the spray is carried with greater pressure than the exhaust.

What we claim as new is In locomotive spark-extinguishers, the pipe Gr, provided with a flaring mouth and passing through both the smoke-box and boiler-shell, in combination with the boiler, smoke-box, smoke-stack, and valved pipe E, the latter having a widened mouth covered with perforate plate and curved over inwardly, all constructed and arranged substantially as shown and described.
